Will be there later this month with 4 grandkids in this range, and would like to find locations good for the whole gang. There is of course Luxembourg Gardens, and on a recent visit, I chanced by the one at Square Rene LeGall which looked pretty suitable. Other suggestions most welcome.

The Jardin Nelson Mandela at Les Halles has playgrounds sorted by age. The biggest playgrounds are at the Parc de la Villette.

While there is no playground the trails and exploring are wonderful. There is also a zoo.

We came across a playground near the Marché des Enfants Rouges which our toddler grandson enjoyed.

There was another at the Parc Monceau, which is also an interesting place for adults.

So that's two in very different areas of the city.
